目前全球對石油的需求量依舊增加,因此世界各地紛紛將研究發展聚焦於此,汽車長期以來使用石化燃料做為動力來源,但近年來各國逐漸重視石油耗竭的危機。然而乳化燃料改善此問題雖是一種可行方案,但是使用乳化燃料,會提升柴油引擎的BSFC和降低引擎馬力。因此本研究使用3 %、5%和8%水分比例的乳化生質柴油中添加100 ppm奈米Al2O3作為燃料添加劑,製成奈米Al2O3乳化生質柴油使用於單缸柴油引擎進行實驗。實驗結果顯示,B10W3A100、B10W5A100、B10W8A100的BSFC總平均值分別比B10生質柴油高出3.75%、5.68 %、8.42 %。定量奈米Al2O3乳化生質柴油中的水分越多,BSFC、HC排放表現越差,但BMEP、Smoke和NOX排放及EGT值有明顯的改善。
In recent years, countries have also stepped up efforts to develop smart vehicles. To provide more efficient services and respond to green energy policy. Many experts and scholars have added emulsified fuel to diesel engines for testing. Water droplets in emulsified fuels are prevented from directly contacting the engine by mingling emulsifiers and causing internal rusting. However, although it can improve the combustion efficiency and reduce the emission of NOx, it also reduces the calorific value due to the presence of moisture, resulting in more fuel consumption. Therefore, adding metal nanofluids can improve its combustion characteristics. we can use this to improve the combustion characteristics of emulsified fuels in order to save fuel and reduce the emission of polluting gases.
